From 5bbde1a63071c17b11f01132030ac15a8e803755 Mon Sep 17 00:00:00 2001 From: Yuedong Du Date: Sat, 11 Oct 2003 03:00:59 +0000 Subject: add new files. set the right role. new file. 2003-10-11 Yuedong Du * gal/a11y/e-table/Makefile.am: add new files. * gal/a11y/e-table/gal-a11y-e-cell.c: (gal_a11y_e_cell_construct): set the right role. * gal/a11y/e-table/gal-a11y-e-table-item-factory.c: new file. (gal_a11y_e_table_item_factory_get_accessible_type), (gal_a11y_e_table_item_factory_create_accessible), (gal_a11y_e_table_item_factory_class_init), (gal_a11y_e_table_item_factory_init), (gal_a11y_e_table_item_factory_get_type): factory for the table item a11y object. in create_accessible, we judge the type of widget then set correct role. * gal/a11y/e-table/gal-a11y-e-table-item-factory.h: ditto. * gal/a11y/e-table/gal-a11y-e-tree-factory.c: new file. (gal_a11y_e_tree_factory_get_accessible_type), (gal_a11y_e_tree_factory_create_accessible), (gal_a11y_e_tree_factory_class_init), (gal_a11y_e_tree_factory_init), (gal_a11y_e_tree_factory_get_type): factory for a11y object of etree. Mostly copyed from gal-a11y-e-table-factory.c. * gal/a11y/e-table/gal-a11y-e-tree-factory.h: ditto * gal/a11y/e-table/gal-a11y-e-tree.c: (init_child_item), (et_ref_accessible_at_point), (et_get_n_children), (et_ref_child), (et_class_init), (et_atk_component_iface_init), (et_init), (gal_a11y_e_tree_get_type), (gal_a11y_e_tree_new):a11y object for etree object, mostly copied from gal-a11y-e-table.c. init_child_item set correct role for the table item. * gal/a11y/e-table/gal-a11y-e-tree.h: ditto. * gal/e-table/e-table-item.c: (eti_class_init): register factory for table item a11y object. * gal/e-table/e-tree.c: (e_tree_get_item), (e_tree_class_init): add new access fuction to get the table item of etree. * gal/e-table/e-tree.h: ditto svn path=/trunk/; revision=22867 --- a11y/e-table/gal-a11y-e-tree.c | 158 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 158 insertions(+) create mode 100644 a11y/e-table/gal-a11y-e-tree.c (limited to 'a11y/e-table/gal-a11y-e-tree.c') diff --git a/a11y/e-table/gal-a11y-e-tree.c b/a11y/e-table/gal-a11y-e-tree.c new file mode 100644 index 0000000000..14546bedda --- /dev/null +++ b/a11y/e-table/gal-a11y-e-tree.c @@ -0,0 +1,158 @@ +/* + * Authors: Yuedong Du + * + * Copyright (C) 2003 Ximian, Inc. + */ + +#include +#include "gal-a11y-e-tree.h" +#include "gal-a11y-util.h" +#include +#include + +#define CS_CLASS(a11y) (G_TYPE_INSTANCE_GET_CLASS ((a11y), C_TYPE_STREAM, GalA11yETreeClass)) +static AtkObjectClass *parent_class; +static GType parent_type; +static gint priv_offset; +#define GET_PRIVATE(object) ((GalA11yETreePrivate *) (((char *) object) + priv_offset)) +#define PARENT_TYPE (parent_type) + +struct _GalA11yETreePrivate { + AtkObject *child_item; +}; + +/* Static functions */ + +static void +init_child_item (GalA11yETree *a11y) +{ + GalA11yETreePrivate *priv = GET_PRIVATE (a11y); + ETree *tree = E_TREE (GTK_ACCESSIBLE (a11y)->widget); + ETableItem * eti; + + g_return_if_fail (tree); + eti = e_tree_get_item (tree); + if (priv->child_item == NULL) { + priv->child_item = gal_a11y_e_table_item_new (ATK_OBJECT (a11y),eti, 0); + priv->child_item->role = ATK_ROLE_TREE_TABLE; + } +} + +static AtkObject* +et_ref_accessible_at_point (AtkComponent *component, + gint x, + gint y, + AtkCoordType coord_type) +{ + GalA11yETree *a11y = GAL_A11Y_E_TREE (component); + init_child_item (a11y); + return GET_PRIVATE (a11y)->child_item; +} + +static gint +et_get_n_children (AtkObject *accessible) +{ + return 1; +} + +static AtkObject* +et_ref_child (AtkObject *accessible, + gint i) +{ + GalA11yETree *a11y = GAL_A11Y_E_TREE (accessible); + if (i != 0) + return NULL; + init_child_item (a11y); + g_object_ref (GET_PRIVATE (a11y)->child_item); + return GET_PRIVATE (a11y)->child_item; +} + +static void +et_class_init (GalA11yETreeClass *klass) +{ + AtkObjectClass *atk_object_class = ATK_OBJECT_CLASS (klass); + + parent_class = g_type_class_ref (PARENT_TYPE); + + atk_object_class->get_n_children = et_get_n_children; + atk_object_class->ref_child = et_ref_child; +} + +static void +et_atk_component_iface_init (AtkComponentIface *iface) +{ + iface->ref_accessible_at_point = et_ref_accessible_at_point; +} + +static void +et_init (GalA11yETree *a11y) +{ + GalA11yETreePrivate *priv; + + priv = GET_PRIVATE (a11y); + + priv->child_item = NULL; +} + +/** + * gal_a11y_e_tree_get_type: + * @void: + * + * Registers the &GalA11yETree class if necessary, and returns the type ID + * associated to it. + * + * Return value: The type ID of the &GalA11yETree class. + **/ +GType +gal_a11y_e_tree_get_type (void) +{ + static GType type = 0; + + if (!type) { + AtkObjectFactory *factory; + + GTypeInfo info = { + sizeof (GalA11yETreeClass), + (GBaseInitFunc) NULL, + (GBaseFinalizeFunc) NULL, + (GClassInitFunc) et_class_init, + (GClassFinalizeFunc) NULL, + NULL, /* class_data */ + sizeof (GalA11yETree), + 0, + (GInstanceInitFunc) et_init, + NULL /* value_tree */ + }; + + static const GInterfaceInfo atk_component_info = { + (GInterfaceInitFunc) et_atk_component_iface_init, + (GInterfaceFinalizeFunc) NULL, + NULL + }; + + factory = atk_registry_get_factory (atk_get_default_registry (), GTK_TYPE_WIDGET); + parent_type = atk_object_factory_get_accessible_type (factory); + + type = gal_a11y_type_register_static_with_private (PARENT_TYPE, "GalA11yETree", &info, 0, + sizeof (GalA11yETreePrivate), &priv_offset); + g_type_add_interface_static (type, ATK_TYPE_COMPONENT, &atk_component_info); + } + + return type; +} + +AtkObject * +gal_a11y_e_tree_new (GObject *widget) +{ + GalA11yETree *a11y; + ETree *tree; + AtkObject * item; + + tree = E_TREE (widget); + + a11y = g_object_new (gal_a11y_e_tree_get_type (), NULL); + + GTK_ACCESSIBLE (a11y)->widget = GTK_WIDGET (widget); + + return ATK_OBJECT (a11y); +} -- cgit v1.2.3
